Bad client service from Game

Bought a TV from Game via online in March 2020. However for the past 2 months the TV has been giving problems. And for the past 2 weeks the TV has been totally black when switched on nothing displaying. I phoned Game to enquire if the TV is still under warranty to check if they can still have a look at to see whats wrong. I provided my consultant with my order number as well as the description of the TV per the emails I received at the time. The consultant informed that she can tell me how long the warranty on the TV is I should phone telefunken and hear from them. if the TV is still under or not. I told her that I dont think telefunken deals directly, with customers like myself, but none the less, I searched on google and tried phoning telefunken without success. It is just a bit dissapointing that the consultant from game couldnt get my order details on the system, told me the system is slow and wasnt able to get the specific details of a product they selling and sold to me to give me clarity if the TV is still under warranty or not. I dont have my original slip but I have my order details per the emails that I recieved as it was an online purchase.Orde number is *** for a telefunken ''55'' Smart FHD LED'.
